C8051F023

Overview

The C8051F023 is a fully integrated mixed-signal System-on-Chip microcontroller from Silicon Labs, featuring a high-speed 8051-compatible core operating at up to 25 MHz. It integrates 64 KB of in-system programmable Flash memory and 4352 bytes of internal data RAM. The device includes an on-chip JTAG debug circuitry for non-intrusive debugging. Key analog peripherals consist of a 10-bit SAR ADC with up to 8 external inputs and a programmable throughput of 100 ksps, two 12-bit DACs, and two analog comparators. Digital interfaces include hardware SMBus, SPI, and two UART ports.

• Fiber optic systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific package type and revision level against project requirements. Check for RoHS compliance status as indicated in official documentation. Ensure supply chain stability by reviewing lifecycle notices such as End-of-Life announcements prior to finalizing procurement plans.

Selection Notes

Select this model when a highly integrated mixed-signal solution is required without external components. The C8051F023 is suitable for applications demanding precise analog-to-digital conversion alongside robust digital processing capabilities. Consider the available I/O count and peripheral set relative to system complexity. Evaluate power consumption characteristics against battery-operated constraints if applicable.

Part Context

This component belongs to the C8051F02x family of 8-bit microcontrollers designed for analog-intensive applications. It shares architectural similarities with other members like the C8051F020, differing primarily in ADC resolution and pinout configurations. The family emphasizes low cost and high integration, targeting embedded control tasks requiring both digital logic and signal conditioning.

Replacement Considerations

Silicon Labs recommends the EFM8BB31F64G-QFN32 as a direct replacement for the C8051F023 due to announced End-of-Life status for the legacy part.
